How to use plant antifreeze and precautions

Plant antifreeze, also known as antifreeze, etc., is a kind of foliar fertilizer containing plant hormones and trace elements. Now many farmers will use it in agricultural production, so what are the methods and points for attention for the use of plant antifreeze? Come and have a look with the editor.

1. Main role

Its main function is to activate biological enzymes, kill or prevent the formation and reproduction of ice nucleus cells, maintain the temperature of biofilm structure during cooling, reduce and reduce the damage of low temperature to biofilm, and reduce the freezing point branches of plant cells. enhance plant water retention and anti-freezing ability, inhibit and destroy frozen protein, increase heat, improve plant resistance to low temperature.

2. When to use it

Plant antifreeze can be used before falling leaves and dormancy in autumn, a week before frost or cold wave, before and after sprouting in early spring, sudden low temperature or freezing injury before and after flowering. Mainly in the flowers and leaves, the temperature of about 10 degrees is the best, less than 5 degrees forbidden to use, generally used 3-5 days before the cold air, in order to improve the stress resistance of plants.

3. Usage

The method of using plant antifreeze is relatively simple, which can be carried out by root irrigation or leaf spraying, generally in late autumn, early winter and spring cold, when the temperature is 10-15 degrees, sprayed every other week, continuous use of 2-3 low. Late spring cold is generally used 3-5 days before the arrival, which can be diluted by 150 times spray or 300 times 400 times root irrigation.

4. Points for attention

Said before the use of fallen leaves and yellow leaves, at this time because of fallen leaves and yellow leaves, most of the plants into the dormancy period, the absorption of plants is not very good, even if sprayed has no effect. Spraying below 5 degrees is prohibited because it is easy to freeze after spraying, which will not only hinder the absorption of plants, but also aggravate the freezing injury. Cooperate with other anti-freezing measures, after the use of plant antifreeze, with other anti-freezing measures, such as soil cultivation, freezing water, trunk whitening, etc., to improve the cold resistance of plants.

The above is an introduction to the use of plant antifreeze and matters needing attention. I hope it can help you. If you want to know more about it, please follow us.
